What'll It Take to Find Life? Searching the Universe for Biosignatures

The supertelescopes are coming, enormous ground and space-based observatories that’ll let us directly observe the atmospheres of distant worlds. We know there’s life on Earth, and our atmosphere tells the tale, so can we do the same thing with extrasolar planets? It turns out, coming up with a single biosignature, a chemical in the atmosphere that tells you that yes, absolutely, there’s life on that world, is really tough.

I’ve got to admit, I’ve been pretty bad for this in the past. In old episodes of Astronomy Cast and the Weekly Space Hangout, even here in the Guide to Space, I’ve said that if we could just sample the atmosphere of a distant world, we could say with conviction if there’s life there.
Just detect ozone in the atmosphere, or methane, or even pollution and you could say, “there’s life there.” Well, future Fraser is here to correct past Fraser. While I admire his naive enthusiasm for the search for aliens, it turns out, as always, things are going to be more difficult than we previously thought.
Astrobiologists are actually struggling to figure out a single smoking gun biosignature that could be used to say there’s life out there. And that’s because natural processes seem to have clever ways of fooling us.
What are some potential biosignatures, why are they problematic, and what will it take to get that confirmation?

Panspermia: Life From Space

We tend to assume that life began here on Earth. But it’s possible that life originated on an alien world and in some form or another was brought here. In this video, we discuss the possibility that life originated somewhere else, either on a planet or asteroid, then spawned life here on Earth.

The potential for life within Enceladus after Cassini

Planetary scientist Dr. Jonathan Lunine of Cornell University discusses the Cassini mission’s exploration of Enceladus and what that moon has taught us about ocean worlds in the outer solar system. Dr. Lunine stresses that Enceladus is the best candidate world at which life may exist beyond Earth in our solar system. This was the third presentation in the Lunar and Planetary Institute’s 2017–2018 Cosmic Exploration Speaker Series, “Diving into Ocean Worlds.”

Will We Ever Find Life on Mars?

Want some great online courses in astronomy? Check out The Great Courses Plus, get one month free trial here: https://www.thegreatcoursesplus.com/DeepAstronomy
Mars is the closest planet to Earth and the most likely candidate to find life in the solar system. So why haven’t we found anything yet? Since 1977 we’ve sent over a dozen space missions to the red planet and haven’t found a single shred of evidence that life once existed. Some researchers think that if life is on Mars it will be found much deeper underground that what our rovers can currently explore. But until we are sending humans to our planetary neighbor we must rely on research from microbiologists and astrobiologists like Dr. Kai Finster.
Tune in this week as we discuss with Professor Kai Finster an astrobiologist from Aarhus University as we dive deep into the topic of finding life on Mars.

*Could interstellar ice provide the answer to the birth of DNA?
Molecules brought to Earth in meteorite strikes could potentially be converted into the building blocks of DNA. A report in the Chemical Communications claims researchers found that organic compounds, called amino nitriles, the molecular precursors to amino acids, were able to use molecules present in interstellar ice to trigger the formation of 2-deoxy-D-ribose -- the backbone molecule, , of DNA.
*The mysterious night side of Venus
The winds and upper cloud patterns on the night side of Venus have been characterised for the first time- giving scientists some surprising results. A report in the journal Nature Astronomy claims the atmosphere on Venus’ night side behaves very differently to that on the side of the planet facing the Sun -- exhibiting unexpected and previously-unseen cloud types, morphologies, and dynamics -- some of which appear to be connected to features on the planet’s surface.
*WASP 19B an inferno world with titanium skies
Astronomers have detected titanium oxide in an exoplanet atmosphere for the first time. The findings reported in the journal Nature show the planet’s atmosphere contains small amounts of titanium oxide, as well as water and traces of sodium, alongside a strongly scattering global haze.
*Charmonium surprise at the Large Hadron Collider
The LHCb experiment at the world largest atom smasher – the Large Hadron Collider has surprised physicists by providing unprecedented precision measurements of the masses of two charmonium particles – something never previously achieved at a hadron collider – and until recently thought impossible. Until now, precise research into charmonium particles required the construction of dedicated experiments to examine this invaluable source of insights into the subatomic world.
*Dragon splash down
A SpaceX Dragon cargo ship has splashed down in the Eastern Pacific Ocean southwest of Long Beach California carrying just under two tonnes of equipment and completed science experiments from the International Space Station. The capsule contained a numerous technological and biological experiments including a team of astronaut mice taking part in micro gravity experiments.
*The Science Report
A new study estimates there are over two billion species of life on planet Earth at the moment.
Warming oceans causing faster Antarctic glacial melt.
Women with coronary heart disease are less likely to achieve treatment targets than men.
Livestock reserve land providing a haven for native plant species.
The rare state of matter in which electrons in a superconducting crystal organize collectively.
Absolutely Fabulous closer to the truth than most want to admit with new studies showing today’s teens aren’t nearly as wild as their parents were.

The Origin of DNA Might Have Came From Space

The origin of DNA might have came from space. How life formed on earth is a mystery the human race has been trying to solve for centuries. What prompted the growth of life on earth? Did it form here? Or did it come from somewhere else? These questions may have an answer, as new studies suggest that the building blocks of DNA could have come from space.
Did DNA essentially come from space? Tell us in the comments below. If you enjoyed the video please hit that like button. Also, remember to subscribe for more videos just like this one.

A Quick Look at GJ 176

Scientists are using X-rays to determine the hospitability of stars for life on exoplanets.
Data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton were used to study 24 stars like our Sun that were at least one billion years old.
They found these older stars had lower levels of X-rays — and hence magnetic activity — than other types of stars.
This relatively calm is good news for life trying to form on planets around these stars.
Astronomers will continue to look at different properties, including X-rays, to assess the best place to look for life outside our Solar System.

In 1990, an experiment conceived by Carl Sagan was performed using using the Galileo spacecraft. The purpose? To detect life on a planet based on measurements by a space probe. The experiment was successful, and abundant life was unequivocally confirmed. That planet? The Earth. Now, a quarter century later, we’re on the verge of conducting that same experiment on a world orbiting another star.

Alien life potentially forming on Saturn’s Moon. Alien life has been a constant topic of debate for many centuries. Some believe we have already been visited by extraterrestrial life, and others believe that notion of aliens existing is pure fantasy. However, with our universe expanding as fast as the speed of light, there has to be something other than us out there right? Recent scientific findings suggest we may have found evidence of otherworldly life in our own solar system. Watch the video to learn more.

We're All Stardust -- And Why That Should Make You Feel Awesome | Dr. Natalie Hinkel | TEDxNashville

According to Planetary Astrophysicist Dr. Natalie Hinkel, exploring outer space makes us realize all of the possibilities for galaxies, stars, planets -- even life. The basic elements created within stars, or the raw ingredients required for life on Earth, needed to be present at exactly the right times in order for humans to exist -- which is pretty empowering, when you think about it.
Dr. Natalie Hinkel is a researcher at Vanderbilt University, studying the composition of nearby stars and how that may affect the make-up of planets orbiting those stars. She got her bachelor’s degree in physics and math at Oberlin College. Her work has brought to light a number of important (and technical) truths within the field, which she has sought to explain by leading multiple international collaborations. Natalie also observes planets that are outside of the solar system, or exo-planets, by using the Cerro Tololo Interamerican Telescope in Chile. She has studied exotic systems where planets. Her PhD is in Astrophysics from the School of Earth and Space Exploration, which combines the fields of geology, planetary science, and astronomy, at Arizona State University. Natalie has put together the largest catalog of element abundances measured in stars near to the Sun, called the Hypatia Catalog; it contains +65 elements in over 6000 stars: https://www.youtube.com/watch?v=lbYYcZtRiXE

Chemicals for Life Found on Enceladus

Did you hear that NASA just announced an important discovery in the quest to find life on other places in the Solar System? In this quick episode, Fraser details what NASA found on Enceladus and Europa, and what it means for the search for life.

I know, I know, this is getting comically hilarious. Aliens, next episode.
Although maybe, aliens this episode?
Anyway, NASA made a huge announcement today, and I thought it was important enough to stop everything we were doing, call Chad and Karla back to Universe Today headquarters to help me cover it.
Here’s the announcement: NASA announced today that they’ve found an important chemical for life - hydrogen gas - blasting out of Saturn’s icy moon Enceladus. In addition to this, they confirmed that Jupiter’s Europa has icy geysers too.
We’ve known about Enceladus’ plumes for a while, so the discovery of hydrogen gas is pretty exciting. We’ve suspected Europa has jets, but more confirmation of their existence is great. We don’t know if there’s hydrogen gas in Europa’s plumes… yet, but there’s a spacecraft in the works to help us find out.
Let’s get into the details.
Earlier this week, NASA teased us that they were going to be announcing something interesting about the ocean worlds of the Solar System. They were vague on details, but Mike Brown confirmed what I’d always expected: Europan Space Whales.
I was all ready to hear their mournful songs, muffled by kilometers of ice, but I was sadly disappointed.
Okay fine, the reality turned out to be pretty cool too. NASA announced that they’ve found evidence that there’s hydrogen gas pouring into the water of one of Saturn’s icy moons: Enceladus. The source of this hydrogen is probably some kind of hydrothermal activity down beneath the ocean.
The tidal interactions between Enceladus and Saturn heat up the moon, giving it vast oceans, which spews water into space from cracks at its southern pole.
Here on Earth, remember, wherever we find water, we find life. And one really interesting place that we find life is surrounding volcanic hydrothermal vents at the bottom of the ocean. These volcanic vents belch plumes of material into the ocean, and serve as the energy source for a vast array of lifeforms.
Heat loving thermophilic bacteria known as methanogens absorb the hydrogen coming from these vents and use them as an energy source. Other creatures eat this bacteria, and you’ve got a thriving ecosystem and food chain.
One of the most interesting things about these hydrothermal vents is how they provide a completely separate ecosystem from the rest of life on Earth. They couldn’t care one bit if the Sun disappeared tomorrow, and all life died. They’d keep slurping up their hydrogen gas, going and going.
And that’s why this discovery about Enceladus is so exciting. In their announcement, planetary scientists working with Cassini described how the spacecraft detected this hydrogen gas in the plumes blasting out of Enceladus.
On October 28, 2015, the spacecraft made its deepest dive through the plumes coming out of Enceladus. It sampled the icy material and found that 98% of the plumes is water, 1% is hydrogen, and the rest is a mixture of ammonia, methane and carbon dioxide.
Cassini isn’t equipped to search for life. It just doesn’t have the instruments on board. Its Ion and Neutral Mass Spectrometer instrument did the next best thing. It found food for bacteria. When this environment is found on Earth, bacteria has a feeding frenzy.
That’s pretty exciting. The discovery over on Europa is different. Astronomers had suspected there were plumes on Europa like Enceladus, based on images taken by the Hubble Space Telescope back in 2014. But the results were inconclusive.
The Hubble team took a second round of images in 2016, and detected plumes coming from the same region of Europa, confirming their existence. Is there hydrogen gas in those plumes too? We have no idea yet, but we soon will.
In a second, I’m going to explain what we’re going to do about this. What plans are in place to study this even further, but first I’d like to thank Khaled Al Tal, Isaac Arthur, Lee Stuurmans, Larry Johnson, Ryan Williams, and the rest of our 705 patrons for their generous support. If you love what we’re doing and want to help out, head over to patreon.com/universetoday.
Now we see another tantalizing clue that there could be life in the oceans of Europa and Enceladus, what are we doing to do about it? What plans are in place to go back and study these worlds up close?

Watch the talented Reggie Watts perform at the Exploratorium August 9th, 2012. Reggie was at the Exploratorium for an Osher Fellowship, and he graciously joined us at the end of a live webcast on Mars to share a little of his own feelings about the red planet!
